Turning Radius

Hey guys,
Does anybody know what the degree markings are and which ones are 10 degrees, 15 degrees, 30 degrees etc?

Correction, the big marks are 30 degrees each.


It’s 10 degrees for each bar :).
The formula for the turning radius is the following.

R = (v^2)/(11.26tan(ß))


  • R being the radius
  • v being your true airspeed in kts
  • ß being the bank angle in degrees
  • (11.26 being the conversion factor for the units involved, (incase you’re wondering))

Hope that helped!


Exactly. 10° for each small bar and the big bars are 30° each


Oh. So that’s what the formula is. That was the day I didn’t pay attention in math class. I just googled my answers. I guess I was a bad student. 😂


10, 20, 30, 45, 60. Just like IRL according to G-Metre.

Yes. That is correct. But I think the original poster was referring to the other lines that arc across the top

Copy. Thank you

So the last two bars would be 40 and 50 right?

Use 15-20 degrees while climbing and turning or descending and turning , 30 degrees for straight and level turns. 45 degrees for steep turns

I believe that 45° gives about 1.41G, so better do it when everyone is sitting at the back!
60° should give 2G! So better do it when there is no back!

I asked this a few months ago, answers here helped.

so the last 2 on the sides are 40 and 50 correct?

Yes! Just take it as the tool used at school to learn about and measure angles.

What does the rest (^) mean?

Square of V.

It’s used to signify the superscript for exponents used when written freehand. For example 3 cubed would be written with a normal three with a superscripted 3 next to it. But since that’s not usually possible iwithout the formatting of a word processing program, it’s written 3^3 instead.

In this particular equation it just means v-squared. So if TAS were 100 knots (for ease of calculation), v^2 would be 100 times 100, or 10,000.

As posted previously in the thread linked above:

A rough rule of thumb is 15% of your true airspeed (TAS)

So 100kts would be 15 degrees, 200 kts 30 degrees and 220 kts (holding speed in a big jet) 22+11 = 33 degrees.

Worked pretty well for me in the past! ;D

And what about the pitch degrees?
